In the manufacture of steel doorsof the type shown in said Barrows patent, many minor variations are encounterd. For -inn stance, the width or height of the door may:

` vary a few inches in order to accommodate the variable sizek dooropenings of box fears. Further,v differentrailroads employy different fixtures for hanging the ,doors andlthese different fixtures frequently necessitatel variations in the upper and lower *portionsv ,of lthe door in order to permitthe attachment; of the fixtures thereto. Also, as will beseen by reference tol said` Barrows patent, the

panels themselves vary somewhat, it beingm observed that the middle panel has thever-kv l -tical edge corrugations 23' thereofextending through the upperandlower marginal edges of the said panel whereas, in the case A.of theV Yupper and lower panels A and vC,-the Vertical edge corrugations 22 andV 231 only-extend to La one horizontaledge of the panels. y Y

Y. when in a cutting machine', the bottom 'plan Y lVhile Figures l and 7 are bottom plan Views, the remaining figures are shown to illustrate the parts as the same will actually appear Views beingV shown to better illustrate the assemblies.;

In carrying out' my inVentiom-in'the pre Vferred form illustrated, I employ four nia-in fram@ s @stens Ae, eed B-B; four nterchangeable corner f-ramesections C-C'l', 1nterchangeable side extension frame sectionsk D-D; and interchangeable end extension-V frame sections E-E.

The two main frame'.V sections rire-AL are Y allke and also the two sections Be-B are alike,

The Ycorner sectionsG, shown in thedraw-A ing, are all illustrated 'as ofY "like forni and tl1e"'part1cular form illustrated is that adapted for shearing aV door panel where the edge corrugation of the latter extends to both edges'ther'eof, forinstance, a panel section such as shown at B 1n said Barrows Patent No. 1,342,400.Y Asf shown, eaehlsaid corner section is in the form of a generally rectanguflar'- casting having four upstanding vverticalfianges 23'5-24-25 and 26. The corner seotion also has VVabottommain web lor plate 27 adaptedf to seat 'on the bed The twofianges 23 and 2d f Figure l)` VarefeXten-ded at.V right angles to each other/and' fit against vthe vertically extending ang'es ofthe-main sectlonswlnfeh define the re-entrantcorner angle 14 hereinbefo-re mentioned and are adapted'to bebolted thereto asvby'bolts 28-28. The other vertical flanges 251and- 26 are specially formed to receive the' knives as hereinafter described In' addition, each corner section C isprovided with two outwardly extended horizontal bottom flanges 29 andB'O, perforated and adapted toreceive securing Ybolts- 31e-3l for attaching to the main or B,=as the case may be. .Y Y,

Referring'more particularly to' Figures 5 and 6, it will be seen that the fiange 25 oi the section. A

corner section isle'Xtend'ed upwardly (or` downwardly depending upon the manner' in which the device is viewed) beyond the genf eral plane of the remaining flanges as-indiscated? at 32, the extensonzz being of a forni to Correspond roughly-with'-tli-e cross-section- Y o'cf'th'e'; corrugat'ion in the panel; Said'flange 25-is1r`abbeted onfitfs'ffouter side as indicated at r33 so as to provide a'se'ating face for the knife or'v cu'tteri which is of a length. cor-y responding'to the'length of. thel side of the corner sectio'mfsfaid knife-34. being specially shaped with an' outstanding projection 35 corresponding tothe corru'gation inthe panel where. the shear is'to be made. Said linife'f.

is secured in 4place by the machine bolts 36.

The otherV vertical knife holdin g fiange 26 of the corner section isfmade somewhat shal-v lower than' the reinaininganges andi provided with a atsurface 3611:, v'which providesa seat for a horizontally" disposedIknife'j secured' thereto by 'counter-sunk. machine screws 38. Theactiye cutting edge of the'l knife 37Vis" made flush Ywiththe adjacent'-p'or'- tion ofv the cutting'edgefof the' knifef34`,:it

ybeing observed that the two knives 34 andl-J,I Y while extending generallyv at right angles toea'ch other are disposed` in two planes at.

thefother" horizontal, thereby adapting lthe y sections A and B but areterminated a short` fue:

corner section to make acleancontinuous cut atfthe corner 'off the panel while accommodating the corrugation inthe panel.

ln someins'tances,fthe corner sec-tions will be iot different' 'knife edge contour than the onejust described, where the same rare to be' used, -for instance, in'cutting panels or sheets that fdo"v not havecorrug'ations 'extending to the"edgesand it Willbeunderstood thatl all of the corner sections with these various modifi-Y cations therein are interchangeable.

Figure l shows the vcutting die assembledV for operationvonf minimum size sheets or panels. VF igu'ref` shows the die expanded for taking a larger lsheetl iboth longitudinally andY laterally. To accomplish this, the Vextension sectins D `and E are' employed, or some of the'InL AReferringto the sections D, each of the latter comprises a "g'eznerally'V elongated casting :having a'vertical flange 38 integral .with a'bottomvvebf or; plate sectionBQ, which ertends 'to Vboth s'desfofthe zflange 38 as shown best inFiguresf? "and 8. Said flange 38-i`s braced on its inner? side by a plurality of ver- `tically"extendingfribs 40e-4l, the end ribs 40 being yadaptedtobe' abutted against the adjacent'portions of the main sections and bolted thereto asbytheloolts 42. Similarly on the outers'ide, additional ribs 43 are provided adapted to be Vbolted tothe corresponding ribs '19.'ofthe mains'ections'." By having eX- tension sections -D of diiierent lengths, itis evidentthat.thei die .cani be extended lengthwisefto any'des'ired'extent. f Y Theend extension frames E are similar in all respects to the eXtension'sectionsD and L the ianges 12 and 13 of the Vmain sections is rabbeted (see Figure 4, ,as indicated' at 44) -to form a knife receiving seat. Knives 45 are securedto'these seats and it will beobser'ved (see Figures 2 and 3) that these Aknives are extended at the corners to a point adapted to abut the corresponding `knives of the ,corner sections C, as indicated Vat 46 and with the vactive edges of the knives flush withthe corner section knives. Said knives 45 are secured bybolts 48. However, the knives 45 are not extended -to the partition-lines ot the main knives 45 are bridged by the gap bridging knives 51--51, each. being secured in position by two bolts 52', one to kone main section and. the other to l, the corresponding adjacent holding seats.

Amainl section. rInthis manner, it will be ob served that thefcuttingl knives 45 do not have to be disturbed or changed when any expansion'zot the :dies is made., In. furtherance terminate shortof the ends of the extension section Vas indicated at 54s`o that similar or the same gap bridging knives 51 may beeinployed and secured" in likemanner` to the main sections and extensionsections to com! plete the knife cutting edge: Inrotherwords, when the die is expanded and an extensionsection inserted, it is vonly necessary to secure a short section of knicteto completelthe cutting edge, thus reducing the *amount of labor and time required in effecting a change; Y .I have not deemed it necessary toillustrate any female die since this may be of any Well known construction so long as it is ofv eX- pansible type to adapt it for co-.operationwith the improved malefdie in i conditions. l ,l

From the preceding description, it will be seen that'my improvements permit the cutting of sheetsor panels havinga Wide rangej of variations as to length or width and vcontoursat the corners,1all changes being effected with a minimum amount of labor and time any of its adjusted.
